playLoop
public void playLoop()Play this sound repeatedly in a loop. If called on an already looping sound, it will do nothing. If the sound is already playing once, it will start looping instead. If the sound is currently paused, it will resume playing from the point where it was paused.
stop
public void stop()Stop playing this sound if it is currently playing. If the sound is played again later, it will start playing from the beginning. If the sound is currently paused it will now be stopped instead.
pause
public void pause()Pauses the current sound if it is currently playing. If the sound is played again later, it will resume from the point where it was paused.
Make sure that this is really the method you want. If possible, you should always use stop(), because the resources can be released after calling stop(). The resources for the sound will not be released while it is paused.
